+# LangGraph for Swift
+🚀 LangGraph for Swift. A library for building stateful, multi-actor applications with LLMs, built on top of [LangChain-Swift]. 
+> It is a porting of original [LangGraph] from [LangChain AI project][langchain.ai] in Swift fashion
+
+
+## Adding LangGraph for Swift as a Dependency
+
+To use the LangGraph for Swift library in a [SwiftPM] project, add the following line to the dependencies in your `Package.swift` file:
+
+```Swift
+.package(url: "https://github.com/bsorrentino/LangGraph-Swift.git", from: "1.0.0"),
+```
+Include `LangGraph` as a dependency for your executable target:
+
+```Swift
+.target(name: "<target>", dependencies: [
+    .product(name: "AsyncAlgorithms", package: "swift-async-algorithms"),
+]),
+```
+
+Finally, add `import LangGraph` to your source code.
